Significance of the Ikenotaira Interstadial Indicated by Moraines on Mt. Kumazawa of the Kiso Mountain Range, Central Japan

From tephra cover on the outermost moraine in the Ikenotaira cirque on Mt. Kumazawa of the Kiso mountain range, a small amount of air-borne scoria from Ontake volcano was collected. The scoria is identified with that of the scoria-fall deposit Sc-I which within the section of the air-laid Younger tephra unit of the so-called Shinshu Loam Formation lies in the basal part. The radiometric age of the Kisogawa volcanic mudflow associated with the Sc-I approximates 27,0001t C years ago, indicating that the outermost moraine be assigned to the pre-Paudorf glacial stade, whereas the upper two moraines should postdate the Paudorf interstadial. The interval indicated between the lower two moraines is emphasized to establish the Late Quaternary chronology. The date of the Ikenotaira interstadial also supports that simultaneous uprise of sea level may have taken place.Article信州大学理学部紀要 1(2): 97-113(1967)departmental bulletin pape

Classification and Correlation of Shin shu Loam in the South Shinshu Tephrogenetic Region, Central Japan

This is a preliminary report of somewhat an essential part of tephrochronological study mainly made in the Ina valley since the last publication of our paper (KOBAYASHI and SHIMIZU, 1962). Tephrochronological study thus being carried in this district and its environs presents for further studies such many clues as micro- and mega-fossil flora closely associated with tephra horizons. These clues may permit us to get detail chronological and climatological informations from the Quaternary events in these districts. Our study has been advanced through only stratigraphic works, except for a few radiocarbon dates obtained from very limited samples. The purpose of the present paper includes the presentation of a chronological base for further studies. Anyhow, it is stressed from our study that no indications of warmer climate have been detected within a sequence of deposits younger than the period when the Wakamiko-Shinmachi plant beds were deposited. Additionally, the Pm-I has well been traced into the Shimosueyoshi Loam which conformably covers the surface of the Shimosueyoshi formation-a transgressive deposit (KOBAYASHI, 1965 a, b). Hence, the Shimosueyoshi marine transgression should be understood as the last major transgression having occurred during Pleistocene time. Exact stratigraphic situation of the Older Loam unit has remaind for future studies, owing to a few exposures and an intensive weathering of primary minerals contained in it. We have obligations to record kind helps offerred by two geobotanists, Dr. K. SUZUKI, Department of Geology, Fukushima University, and Dr. S. KOKAWA, Department of Botany, Osaka City University. We are also indebted to Mr. Y. GOHARA of our Department of Geology, and to Dr. S. KAWACHI, Mr. T. KOBAYASHI, Mr. K. KITAZAWA, and Mr. T. NASU for their cooperation.ArticleJournal of the Faculty of Liberal Arts and Science, Shinshu University. Part 2, Natural science 15: 37-59(1965)departmental bulletin pape

The variability in abundance of eugregarines living in the Antarctic krill

The variability in abundance of eugregarines associated with the Antarctic krill Euphausia superba was studied using samples collected from the vicinity of the Antarctic Peninsula. Body length, maturity stage and moult stage with respect to variation in eugregarines infection in krill were examined. Body length was significantly correlated with abundance of eugregarines. The interaction between moult stage and maturity stage was statistically analyzed by ANCOVA with body length as the covariate. The analysis of moult stage did not show a significant effect on abundance of eugregarines while the interaction between maturity stage and body length showed significance. Larger krill have more eugregarines than smaller krill at the same maturity stage. Body length appears to be the most important factor determining the abundance of eugregarines
